Leaky air ducts can cause problems. These leaks can add to a host of other problems that will end up costing money and can be bad for your health too. To avoid these problems, you need to make sure the air ducts are sealed. This will prevent any problems with airborne contaminants entering your home through the ducts and compromise your health. Properly sealed air ducts will also conserve heating and cooling costs by limiting unnecessary energy loss. The average home loses 25% – 40% of the air circulating in it through leaks, holes and poor connections. Older homes need to have their duct systems inspected regularly to look for any problems.
Signs of Bad Ductwork & Leaking Air Ducts
• Unreasonably high utility bills
• Exposed ductwork in crawlspaces, basements, attics and garages
• Kinks or sharp bends in ductwork
• Rooms that feel stuffy
• Rooms that are hard to keep cool in the summer and warm in the winter
• Lots of dust in your home, even though you clean regularly
Health & Other Negative Effects of Leaking Air Ducts
If you have asthma or allergy sufferers in your home, you need to be concerned about leaky air ducts. Leaky air ducts can make it harder to breathe and can become a dangerous because they allow contaminated air to circulate with conditioned air, allowing unwanted contaminates in your home. This contaminated air can contain allergens and other dangerous fumes including:
• Dust, pollen, and other airborne particulates
• Moist air that can lead to mold and mildew growth
• Vapors from cleaning agents and other substances that can be harmful
• Exhaust fumes from vehicles and small machines
Added to the health risks, comes the significant waste of energy through leaks. When ducts lose conditioned air, they pull in outside air to replace it. This cause your heating and cooing system to work harder to maintain a room temperature that is comfortable. An overworked system wastes energy and increase the cost-not to mention the wear and tear it will experience.
How to Repair Leaking Air Ducts
If you are experiencing signs of leaky air ducts, you need to call professionals in for an inspection. Trying to seal air ducts yourself can make the situation worse. You can create serious imbalances by sealing bigger leaks, ignoring smaller ones or missing leaks. Another reason you are experiencing problems might be because your system is designed inefficiently and may need to be modified. Hire a company that specializes in diagnosing and sealing air ducts and will assess the energy efficiency and air quality of your home. What can you do? Clean vents and registers regularly to remove accumulated debris and look for any irregularities as well as proper seals between the duct and the wall, ceiling, or floor. Look for crushed, tangled or kinked ductwork that you can see and apply white mastic tape to lose connections and leaks that you can access. Do not use duct tape. It will dry out and deteriorate quickly.
